示例1: newDefaultExpression
import org.eclipse.jdt.core.dom.AST; //导入方法依赖的package包/类
/**
* Returns an expression that is assignable to the given type. <code>null</code> is
* returned if the type is the 'void' type.
*
* @param ast The AST to create the expression for
* @param type The type of the returned expression
* @param extraDimensions Extra dimensions to the type
* @return the Null-literal for reference types, a boolean-literal for a boolean type, a number
* literal for primitive types or <code>null</code> if the type is void.
